Configuration
The configuration is divided into the following categories:
Options
Keys
The configuration is stored in the JSON format in a file located at ~/.term_image/config.json
.
Config Options
They are as follows:
- anim cache
The maximum frame count of an image for which frames will be cached during animation. [*]
Type: integer
Valid values: x >
0
- cell width
The initial width of (no of columns for) grid cells, in the TUI.
Type: integer
Valid values:
30
<= x <=50
and x is even
- checkers
Maximum number of subprocesses for checking directory sources.
Type: null or integer
Valid values:
null
or x >=0
Ifnull
, the number of subprocesses is automatically determined based on the amount of logical processors available. CPU affinity is also taken into account on supported platforms.If0
(zero), directory sources are checked within the main process.
- font ratio
The font ratio. [*]
Type: float
Valid values: x >
0.0
- getters
Number of threads for downloading images from URL sources.
Type: integer
Valid values: x >
0
- grid renderers
Number of subprocesses for rendering grid cells.
Type: integer
Valid values: x >
0
If0
(zero), grid cells are rendered by a thread of the main process.
- log file
The file to which logs are written. [*]
Type: string
Valid values: An absolute path to a writable file.
If the file doesn’t exist the parent directory must be writable, so the file can created.If the file exists, it is appended to, not overwritten.See Logging.- max notifications
The maximum number of TUI notifications that can show at a time.
Type: integer
Valid values: x >=
0
Adjusts the height of the notification bar.- max pixels
The maximum amount of pixels in images to be displayed in the TUI. [*]
Type: integer
Valid values: x >
0
Any image having more pixels than the specified value will be:
skipped, in CLI mode, if
--max-pixels-cli
is specified.replaced, in TUI mode, with a placeholder when displayed but can still be forced to display or viewed externally.
Note that increasing this should not have any effect on general performance (i.e navigation, etc) but the larger an image is, the more the time and memory it’ll take to render it. Thus, a large image might delay the rendering of other images to be rendered immediately after it.
Attention
The version
field is not a config option, it’s used for config file updates and should not be tampered with.
Key Config
The key assigned to every action can be modified in the config file.
The "keys"
field in the configuration holds a mapping containing fields each mapping a context to a mapping of actions to their properties.
The format of the "keys"
mapping is thus:
{
"<context>": {
"<action>": [
"<key>",
"<symbol>"
],
...
},
...
}
‘…’ means continuous repitition of the format occurs.
Hint
If using a Unicode character that occupies multiple columns in symbol, then add spaces after it as required to cover-up for the extra columns.
Note
The navigation
field is not actually a context, instead it’s the universal navigation controls configuration from which navigation actions in actual contexts are updated.
Attention
Keys used in
navigation
orglobal
contexts cannot be used in any other context.All keys in a context must be unique.
If a key is invalid or already used, the default is tried as a fallback but if that fails (because it’s already used), the session is terminated.
